Hey guys I have 2011 MK7 Passat. It has factory RCD 310 DAB and under seat bluetooth module installed. I am after upgrading unit to RCD 510 DAB or RNS 315 DAB.
Most RNS 315 has DAB and Bluetooth build in unit. So my question is, will under seat BT module and RNS 315 BT inter-fear with each-other? Which BT will be functional?
Thanks
